Fuel injector retention arrangement

A fuel injector retention arrangement for connecting a fuel injector with a fuel rail comprising:

• a receiving cup for the fuel injector, the receiving cup having a fuel rail end in connection with the fuel rail and a fuel injector insertion end into which the fuel injector is insertable;
• at least a first connecting pin, the first connecting pin being insertable into the receiving cup in such a manner, that a longitudinal axis of the first connecting pin is situated at least substantially in a first plane, which is oriented perpendicularly to a longitudinal axis of the receiving cup;
• wherein the first connecting pin is at least partially arranged in a first aperture defined by the receiving cup, wherein a longitudinal axis of the first aperture and the longitudinal axis of the first connecting pin are coaxial to each other;
• wherein the first aperture has an insertion end into which the first connecting pin is insertable and a shoulder forming an axial stop for the first connecting pin at a second end of the first aperture away from the insertion end of the first aperture;
• wherein the first aperture has a service opening which is arranged in the receiving cup between the shoulder of the first aperture and an outside surface of the receiving cup;
• and
• wherein the service opening of the first aperture is defined by:
• a first side surface radially extending away from the second end of the first aperture and the longitudinal axis of the first aperture,
• a second side surface extending along the longitudinal axis of the first aperture and away from the first aperture, and
• a third side surface and a fourth side surface, wherein the first side surface and the second side surface extend between the third side surface and fourth side surface.
